Abstract

The invention discloses a preparation method of a rice-grain-shaped ferric oxide composite cotton carbon fiber material. The preparation method comprises the following steps: (1) dissolving ferric chloride in an absolute ethanol solution, soaking non-woven cotton fiber into the solution, taking out the non-woven cotton fiber, and then, putting the non-woven cotton fiber into a drying box to be dried; (2) putting the dried non-woven cotton fiber into a furnace, introducing protective gas, and keeping the temperature at 600-1100 DEG C for 1-10h; and (3) stopping heating, continuing to introducethe protective gas, and after the furnace temperature decreases to room temperature, taking out the sample, thereby obtaining the rice-grain-shaped ferric oxide composite cotton carbon fiber material.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a method for preparing rice grain-shaped ferric oxide composite cotton carbon fiber material. Background technique [0002] As a member of metal oxides, ferric oxide is an important n-type semiconductor. It has the characteristics of non-toxicity, low cost and simple synthesis process. It is widely used in catalysts, sensors, sewage treatment, electromagnetic interference shielding, microwave Absorption, biomedicine and energy storage fields, and it is expected to develop new uses in more fields in the future. However, ferric oxide is similar to other metal oxides, the conductivity of the material is low, and the overall stability of the material is poor when used alone, so ferric oxide needs to be combined with other materials with higher electrical conductivity to be better exert its performance. [0003] Combining ferric oxide with carbon can effectively improve the stabil...
